Classification Provides Strong Evidence Supporting Darwinian Evolution. Is This True Or False?

I think it is true because classification is also adding a lot to strengthen the theory of evolution by Darwin. Of course classification of organisms is a solid proof of Darwin's theory of evolution. It is showing that how organisms are classified from a lower level to higher one. We have one type of animals in a single category while other types of organisms in the other category. These things are telling that how organisms are moving from lower level of organisms to the higher one. So this gives us an idea that how organisms are moving from one step of unicellular to the next steps of multicellular.

It seems clarified by the classification steps of organisms but still we have doubts, that why we are not going to rely upon it. But time says that we should go with it in every regard. Another thing is that Islam does not approves Darwin theory so some of the scientists say that it is wrong to consider that classification is giving a clue to Darwin's evolution theory but still we have a colossal group giving us a big YES that classification is concerned with Darwin's theory at all.
